WINDOW-CONTROL MECHANISM.

Application filed January 16, 1922. Serial No. 529,485.

'This invention relates to window control mechanism and moreparticularly to devices for controlling the vertically sliding window members of automobiles and other vehicles.

a Said invention is in the natureof an im provementupon applicants co-pendlng application Serial Number 416,245 and consists in the structural features hereinafter fully described and illustratedin the accompany- 1 ing drawings 1 v Figure 1 is an interior view ofan automo- 'bile door having: a window equipped with the improved control mechan ism; Figure 2 is an enlarged view of the control mechanism as shown in Figure 1;-

Figure 3 is a vertical sectional view of the same taken on line 3-.-3 of Figure 2. l

In these views the reference character A designatesan automobile door having in its upper portion the window opening B and provided with a closure for said opening having the nature of avertically slidable glass plate C, adapted in lowered position to enter a chamber D formed in the lower portion of said door. E is a swinging control arm for raising and lowering the plate C, said arm engaging at one end a channel shaped bracket E depending from said plate and being pivotally mountedatits other extremityupon a bracket F secured within the chamber D to one of the uprights of the door. G is a sheet metal pl upon the pivot pin G of the arm E and formed witli'an arcuate series of apertures H selectively engageable by 'a pin H for rigidly connecting said Upon the plate G there is swivelly mounted a nut I which is engaged by a screw threaded stem J extending upwardly and connected by a universal joint K to a shaft Ljournaled in a two part'gear case M. Said gear case is I secured to the lock board N. of the door by screws 0 and the two parts of said case are rigidly connected by screws P. Q, designates a pair of spiral gears mounted within the member M and establishing a drive connection to the shaft L from a relatively transverse stub shaft R having a squared end B for engagement by a control handle S. Suitable means may be provided for counter balancing the plate C as for example the pivotal arm T upwardly urged by a coil i U and engaging at its end benea sai plate.

. swinging ate mounted plate to the arm E.

the operation of the descri e mecha nism when the handle S is turned, the gears I drive the shaft L from said handle and the threaded stem J is rotatively driven from said shaft through the universal joint K. The nut I, being restrained from rotation in unison with said stem, is fed longitudinally of the stem through such rotation rocking the plate G and the arm E to which said 7 plate is rigidly secured. Rocking of. the arm E raises or lowers the plate'C owing to en- 'a 'ement of said arm with the bracket E.

Sil ice the nut Iwhile engaging the stem' J is about the pivot pin J, the free to undergo a slight movement, as well as, a rotative Provision for such movement is made connection of said stem to its drive shaft S through the universal joint K. The con struction is one that permits-the gear box M to be rigidly secured to the lock bolt N and it is to be hermore noted that the location of'the said gear case upon the lock board may be widely varied without affecting the satisfactory operation of the mechanism.

adaptability of the mechanism to be 0perablefrom various points upon the door is required to swing stem J mudt be one.

in cars of difl'erent makes.

Adjust-ability of the plate G relative to the arm E is desirable to establish thewproper limits of travel for the nut I upon the. threaded portion of the stem J.

It will be apparent that the engagement of the stem J with the nut I provides an automatic lock such as will maintain the desired position of adjustment. of the plate C.

The universal joint K, as utilized in the described construction, accomplishes the dual function of permitting the stem J to swing in a plane parallel to the plate C to accommodate thearcuate travel of the nut I, and eliminating necessity for any accurate registration of the plane of travel of said nut L with the vertical plane determined by the shaft L. In other words the employment of 1 0 7 said universal joint permitsthe stem J to swing freely in'any direction, so that any risk of binding due to lack of ali 'nment of the bearings engaged by. the shaft i and that formed by the nut I embracing the stem J is avoided.

What I claim as my invention is 1.-In a window control mechanism, thecombination with a sliding window member, of a pivotal control arm' therefor, an in combination with a sliding window member, of a pivotal control arm therefor,1a rotati've threaded swingin stem for ac- 1 tuating. said arm, a swivell ed nut engaged by said stem for actuating the arm from the stem, and a' member carrying said nut adjustably secured tothe arm.

3. In a window control mechanism, the

combination with a sliding Window member,

lot a pivotal control arm for said member, an actuating element for said arm and a plate engaged by said actuating element copivotal with said arm and angularly adustable relative to the arm about their common ivot.

4. n a window control mechanism, the combination With a sliding window member, of a pivotal control arm therefor, an actuating member for said arm, and a member connected to said arm adjustable transversely of the arm for 'der "arious engagement by said actuating member.

5. In a window control mechanism, the combination with a sliding window ember, of mechanism for actuating said em- .ber, and supporting means for said mech-' a-nism, said mechanism including relatively adjustable members for moving said mem her to a predetermined closed position un positions of said supporting means.

6. In a window control mechanism, the

combination with a frame, a'sliding window member, and sealing 'members upon said frame and window member coo a' predetermined position of adJuStment of of said window member, of mechanism for actuating said window member, and supporting means upon said frame for said mechanism, said mechanism including relcrating ina'tively adjustable members for moving said window member to said predetermined position under various positions of said supportmg means. I

In testimony whereof I afiix my signature.
